We have a cavalier that has a gas smell with no noticable leak. The gas mileage has been about normal but the smell of gas is worrisome. Any ideas on why it might smell like gas? Thanks.

It's probaly a leaking Oring from one of the injector, if the gas smell only noticible in engine running that's the problem, otherwise leak could come from gas steel pipe rusting!!!

Might be an overflowing charcoal cannister. It's located in the right fender well in fornt of the tire. This is part of the emmissions system that recirculates unused gas and gas vapors.

your gas tank might be rotten, mine rotted out on the top and i had to replace it. 1998 z24.

I'm going thru a similar thing (ref my post same page). The gas smell is very noticeable (at times) while stopped, and disappears at highway speeds. I have one injector that shows signs of a leak since dirt has collected around this one injector. However, the auto mechanic (took it to local shop) says he doesn't think the injector is the problem, nor can he find it. I told him to keep the car a day and run an errand with it, the gas smell will be quite obvious.

I think it is the injector, but i'll keep you posted on what he finds.

had this same problem, it was our fuel injectors. hope this helps.

do it yourself please.....my parents did it, cost us freaking $1500, and they blew out my serpintine belt in the process we think.

My 97 2.4 just started doing this today. I think it's either the fitting at the fuel rail or the fuel pressure regulator. My plan, and what you guys might want to do, is to spray some brake clean (or something similar that will dry it out) around the suspect area to totally dry them out. Run it for a time and check where it gets wet.
